GASOLENE-TANK.

Specification of Letters Patent.

Patented June 13, 1911'.

` Application led February 9, 1911. Serial No. 607,686.

To all 'whom it may concern:

Be it known that I, WILLIAM F. SCHWIE- sow, a citizen of the UnitedStates, and resident of Ripon, in the county of Fond du Lac and State ofWisconsin, have invented certain new and useful Improvements inGasolene-Tanks; and I do hereby declare that the following is a full,clear, and exact description thereof.

.My invention consists in whatis herein particularly set forth withreference to the accompanying drawings and pointed out in the claims ofthis specicatlon, its object being to provide gasolene tanks with meansby which to limit the feed of their contents to a predetermined depth,as a reminder that replenishment is necessary, and to thereafter permitfeed of the remaining contents 1f desirable, said invention havingespecial reference to the fuel tanks of gasolene engines for automobilesand otherwise.

Figure 1 of the drawings represents an elevation of a gasolene tankpartly broken vaway and provided with an adjustable device illustratedas set to lirhit feed of the contents of the tank to a predetermineddepth, and Fig. 2, a similar View illustrating said device adjusted topermit feed of the remaining contents of said tank.

Referring by numerals to the drawings, 3 indicates an ordinary gasolenetank, 4 a nozzle-fitting attached to the .bottom of the tank to dependtherefrom, 5 a cock-controlled feed-pipe coupled to the nozzle-fitting,and 6 a cock controlling a drain-extension of said fitting.

Extending through an aperture' in the vtank bottom and havingscrew-threaded engagement with the fitting aforesaid is a hollow plug 7provided with upper and lower apertures 8, 9, a stem 10 of the plugbeing extended througha bearing 11 with which the top of said tank isprovided. The adjustment of the plug is limited in one direction by aflange 12 thereof in opposition to the bottomiof the tank, and in theopposite direction by a stem-collar 13 opposed, to the top of said tank.When the plug 7 is adjusted to the position shown in Flg. 1, thecontents of the tank may feed through the top aperture 8 of said lug tothe predetermined depth indicate The feed being automaticallydiscontinued, the contents of the tank may be replenished if a supply ofgasolene is at hand, otherwise, the plug 7 55 is adjusted to bring itslower aperture into position to permit iow of the remaining contents ofsaid tank, the same being ordinarily sufficient to last an automobiledriver for several miles, thereby giving him opportunity to run on towhere he may again fill the aforesaid tank with gasolene.

. I claim:

1. A. gasolene tank provided with a noz- 21e-fitting connected to afeed-ppe,fahollow' 65 feed-control plug having screwthread .engagementwit-h the fitting and extending int-o the tank, said plug beingapertured adja- :cent to both ends of the-same, and a st em extendingfrom the plug through a bearing with which the tank is provided.

2. A gasolene tank provided with a nozzle-fitting connected to afeed-pipe, a hollow feedLcontrol plug having screw-thread engagementwith the fitting and extending into the tank, said `plug being;apertured adjacent to both ends of the same, a stem extending from theplug through a bearing with which the tank is provided, and means in`connection with said plug and stem for limiting the adjustment of thesame in 0pposite directions.

3. A gasolene tank provided with a nozzie-fitting connected to afeed-pipe, a hollow feed-control plug having screw-thread engagementwith the fitting and extending into the tank, said plug being aperturedadjacent to both ends of the same, a stem extending from the plugthrough a bearlng with which the tank is provided, a stopange on saidplug, and a stop-collar on the stem.

In testimony that I claimthe foregoing I have hereunto set my hand atRipon 1n the county of Fon du Lac andl Stateof Wisconsin in the presenceof two `witnesses.
